What is Open Cell Foam

Open-cell spray foam is an insulation material sprayed into wall cavities, attics, and other spaces, where it expands to cover the region. Open-cell foam is derives its name from the foam cells as they are not completely sealed, allowing air and moisture to pass through. It is sprayed on and expands to fill the gap, forming a seal against drafts and minimizing heat loss. The open cell structure lets air and moisture pass through, making it a perfect material for specific applications. This foam is typically less expensive than closed-cell foam and has a lower R-value, measuring a material’s resistance to heat flow.

Open-cell spray foam insulation is quite cost-effective in enhancing the energy efficiency and comfort of a home or business. This product has several advantages for residential, commercial, industrial, and agricultural structures and is frequently perfect for all such buildings.

Closed Cell Vs. Open Cell Foam

Closed-cell spray foam insulation consists of closed cells with no holes or openings. This foam insulation is denser and provides a higher level of insulation than open-cell foam. Additionally, it is stiffer and has a greater R-value (a measure of resistance to heat flow). Closed-cell foam is explicitly designed to be applied when a high level of insulation is required, such as on walls and roofs.

Open-cell spray foam insulation consists of cells that are not fully closed, contain spaces or holes, and are less dense and rigid than closed-cell foam, and it has a lower R-value and is not as effective as closed cell foam in insulation. Open-cell foam is designed for areas that require less insulation, such as basements and crawl spaces, and when flexible insulation is needed, such as in attics or around pipes and wires.

Open Cell Spray Foam Soundproofing

Open-cell spray foam may not eliminate all noise, but it can significantly lower the sound that travels through walls, floors, and ceilings. Used for various purposes, including spray foam insulation in attics and cathedral ceilings and injection foam insulation in existing walls and ceilings.

Injection foam insulation is an excellent method for soundproofing existing walls without requiring the removal of drywall. Installers can remove a section of siding, drill a hole into the stud cavity, and inject foam into the gap to fill it, which makes it effective in minimizing noise between rooms in internal walls.

Both spray foam and injection foam entirely fill the cavity in which they are installed, making them efficient noise-reducing insulation materials for your home.

Open Cell Spray Foam R Value

The low density of open-cell spray foam renders it vapor-permeable as it is sprayed using carbon dioxide or water as the blowing agent when applied to ceilings, walls, and roofs. Some open-cell foam is partially manufactured from bio-based components, such as soybean oil. With R-3.5 to R-3.6 per inch, it has a lower R-value per inch than closed-cell foam and absorbs and retains water, so in the case that a 2×4 cavity filled with open-cell spray foam should have an R-value of roughly R-13. Closed-cell spray foam has an R-value per inch between R-6.5 and R-7, which you can see is higher than open-cell spray foam. Other insulating materials, such as cellulose, fiberglass, and open-cell foam, have R-values ranging from R-3.2 to R-3.8 per inch. Under slabs, ceilings, walls, and roofs, closed-cell foam is utilized as insulation because it creates an excellent air barrier, resists moisture, and retards vapor. In addition to contributing to the structural integrity of a ceiling, wall, or roof due to its density and glue-like adhesion, it is also effective for sealing air leaks in attics and other locations.

Open Cell Spray Foam Attic

Spray foam insulation with open cells is an ideal option for use in attics. Its fast expansion rate enables it to cover even the tiniest cracks and fissures, creating a seamless and effective insulating barrier. Due to its ability to expand around 100 times its initial size, less material is needed to provide the same amount of insulation, making it a more cost-effective solution than other types of insulation. In addition to its robust insulating characteristics, spray foam with open cells is also highly permeable to water vapor. For example, in the event of a roof leak, the foam insulation will not hold moisture like other insulation materials. The water can instead travel through the foam, preventing the growth of mold and mildew, making open cells spray foam an excellent choice for usage in situations where moisture is an issue. Open-cell spray foam insulation is an ideal alternative for attics and roof decks because of its high expansion rate, affordability, and water permeability. Others in the industry and the manufacturers with whom we collaborate recommend it highly for these applications.
